The new method execte() is necessary because the perform() method declares that it throws only IOException and ServletException. Due to the added declarative exception-hndling functionality, the framework needs to catch all instance of java.lang.Exception from Action class.

Instead of changing the method signature for the perform() method and breaking backward compability, the execute method was added.

The only difference between the two is
execute() throws Expection whereas
perform() throws IOException and ServletException
perform() has now been depricated so one should use execute() only.
